Question

在整个申请过程中，我在几个地方都有回形针。我正在尝试使用我的某个表单上传到附件（两张图片），并且它没有提供任何有用的信息，因为它没有成功上传。我使用了paperclip 4.2.2。

回形针日志如下：

我只看到BEGIN / ROLLBACK尝试。

我的控制器代码：

@listing_information_form = ListingInformationForm.create(listing_information_form_params)
if @listing_information_form.save && @listing_information_form.cancel_loan == nil
  redirect_to business_embedded_signing_path(@user)
elsif @listing_information_form.save && @listing_information_form.cancel_loan == true
  redirect_to business_root_path
else
  flash[:warning] = 'Unsuccessful'
  redirect_to :back
end

private

def listing_information_form_params
  params.require(:listing_information_form).permit(:business_id, :terms_acceptance, :logo_url, :picture_url, :business_profile, :loan_id, :loan_name, :logo, :loan_image, :cancel_loan)
end

我的模特：

has_attached_file :logo,
    :styles => { :original => "90x90" },
    :storage => :s3, 
    :url => ":s3_domain_url",
    :path => "account/:class/:railsid/:filename"
has_attached_file :loan_image,
    :styles => { :original => "310x202>" },
    :storage => :s3, 
    :url => ":s3_domain_url",
    :path => "account/class/:railsid/:filename"

任何人都可以提供有关Paperclip提供的跟踪的一些信息吗？我将这些文件上传到s3，并且在我的应用程序中没有其他表单上的任何问题。

从问题的评论......

如果您在重定向之前puts @listing_information_form.errors.to_yaml会发生什么？

@ Questifer的回答：

to_yaml向我展示了我应该看到的荒谬错误。它与cancel_loan字段有关。我真的很感谢你帮助我调试这个 - 你为我节省了很多时间和挫折。

很高兴我能帮到你！有时用puts啄食事物可能会有效。

BONUS：我的另一个建议是将save的值缓存在这样的局部变量中，这样您就不会意外地运行save两次：

@listing_information_form = ListingInformationForm.create(listing_information_form_params)
success = @listing_information_form.save

if success && @listing_information_form.cancel_loan == nil
  redirect_to business_embedded_signing_path(@user)
elsif success && @listing_information_form.cancel_loan == true
  redirect_to business_root_path
else
  flash[:warning] = 'Unsuccessful'
  redirect_to :back
end
